See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce GTX 560M SLI

2011

Why buy it

✅32.9% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌2011 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌150% higher power demand at 100W vs 40W.

RadeonT 660M

2023

Why buy it

✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 40W instead of 100W, a 60W reduction.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than GeForce GTX 560M SLI across 50 tracked games in our benchmark data.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 560M SLI is the faster gaming card right now. In our data, it leads by 32.9% in average FPS across 50 tracked games in our benchmark data and by 2.4% in PassMark G3D (2,274 vs 2,221), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

RadeonT 660M is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 40nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2011. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce GTX 560M SLI makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, GeForce GTX 560M SLI is the easier value choice. If you care more about 1080p and some 1440p headroom, RadeonT 660M has the stronger long-term case.
